Tracking HAB BGS1 *Bourne Grammar School, Lincs,*

Hi all. Our Skycademy student-programmed and built balloon will be launched between Wednesday and Friday of this week (looks like Friday at the moment) at 9am. 

We'll be transmitting on: 
RTTY (BGS1): 434.100MHz 



I used VB audio cable software, which allows you to feed the audio from the web SDR to the FLDIGI sound input. Again this is free software and can be downloaded here: http://vb-audio.pagesperso-orange.fr/Cable/

To track this balloon we used a web software defined radio based in Cleethorpes, North East Licolnshire: http://radiogeek.co.uk/ Thanks to Lee G4TNX

Tuned into 434.100MHz USB

The software to decode the pictures and share to Internet is called FLDIGI (HAB mode) you can get a copy here
https://ukhas.org.uk/projects:dl-fldigi

To set up:
DL client--configure--Location tab, look in the information section on the web sdr the Lat and Lon is there please use it.
Operator tab--fill in your call sign or nick name along with other details. Save and close
DL-client---check online is ticket (send your data to the map and to the images web site.
Click on view--ssdv RX, this will show you what bits of the image you have been able to decode

Looking on the HAB tracker website: http://tracker.habhub.org/
We could see *Pinky* and Piglet and were able to monitor their movement.
We could also see our station (MXoMXO) as a pin on the map.

We were able to see the decoded images at http://ssdv.habhub.org/
This site collects all the packets from FLDIGI users and combines them to get the best full image.

Now we are ready to go..

Photograph above from the ssdv web site, takes all monitoring stations decoded packet to makde a complete image: http://ssdv.habhub.org/ You can see our small efforts as call sign MX0MXO


Here is a picture of the balloon tracket page at: http://tracker.habhub.org/ 
You can see 3 different stations were able to receive the balloon including MX0MXO in Cleethorpes!


Full clear images from RTTY feed which we helped to decode



Great image I think this is on the way back down (a bit out of order!)


Another great image

Looks like they made it to near space and got a very nice shot of the curvature of the earth


Recovery successful!
Men in black? No its not a UFO or alien object!
Site clear returning to base.
